Vitamin D and Hair Loss

Who doesn’t like to flaunt shiny, bouncy locks of hair?

But, recently, have you been observing the fine fading hairline? Does the thinning hair putting you to worry? Is your drain getting clogged with an amount of hair that might leave you in shock?

Maybe, your habits and diet are responsible for causing this worry.

Nowadays, the lifestyle of the people has changed. People have started excluding healthy stuff from their diet and replaced a larger chunk of their diet with junk.

Lack of vitamins and minerals lead to deficiency, causing serious health problems.

One of them is loss of hair.

Protein isn’t the only nutrient needed to maintain healthy hair. You also need other vitamins and minerals like iron, vitamin E, vitamin D, selenium, copper, and magnesium to help keep your hair in good shape. “These are all involved in the production of the various proteins that make up your hair,” says Christine Gerbstadt, MD, RD, spokeswoman for the Academy of Nutrition and Dietetics (formerly called the American Dietetic Association).


Vitamin D is a fat-soluble vitamin, present naturally in some foods, while to others, it is added as a dietary supplement.

Apart from its presence in the diet, it is also produced endogenously (produced within the living system) when the skin is exposed to ultraviolet rays from sunlight. This triggers the synthesis of  Vitamin D.

Vitamin D obtained from sunlight, diet, and supplements is in a biologically inert form (inactive form) and must undergo two chemical conversion processes in the body for activation.

There is a strong link between vitamin deficiency and hair loss. If your levels of vitamins are sufficiently low for a sustained period and if your hair follicles are not supplied with the vital nutrients which are needed to maintain a normal hair growth cycle, it can lead to hair loss.

Lacking in these nutrients, your hair can become brittle and susceptible to breakage as your body will become less efficient in the maintaining healthy hair growth.

Researchers studying on the relationship between hair loss and Vitamin D deficiency at Cairo University carried an experiment on women, wherein they found that women who were experiencing hair loss also had lower levels of Iron and Vitamin D2. Furthermore, their woes of hair loss continued and only got worse as the levels dropped.

Rania Mounir Abdel Hay, MD, a dermatologist at Cairo University, and co-author of the study explained that this was the first time that Vitamin D’s possible role in hair loss had been brought into light. Further citing a reasonable explanation, she continued that it (lower Vitamin D levels) might regulate the expression of genes that are responsible for promoting normal hair follicle growth.

A study conducted in the year 2012, whose findings were recorded in the journal ‘Stem Cells Translational Medicine’ which pointed that the vitamin can help create new follicles — little pores where new hair can grow.


Scientific research study has shown that vitamin D can help stem cells to improve and maintain their ability to produce hair. While this does not emphasize the creation of new hair follicles, it may have suggestions for the reactivation of existing follicles in the production of healthy hair.

Soaking in the sun, including Vitamin D-rich foods and supplements strictly under medical supervision might help to alleviate the hair loss problems.
